Winter time model building thread.
I got most of the crankshaft finished today.....apart from needing locater pin holes to mount gears, flywheel, etc......just got to finish clearancing the crankcase for the conrods.....when I get to make them.....:)
The crank is one piece, made from 4140, 38mm diameter ground-to-size round bar. The crank pin is 0.500" diameter......shaft ends are 17mm diameter.....with M6 x 1.0mm threads in each end.
